carrying a pair of springs 25 which are forcibly inserted therethrough preferably as shown in the drawings. Each inclosed or tubular fuse 26 is carried by one spring 25 and one spring 15, one terminal of the fuse,

being inserted through a hole in spring 25 and then depressed against a projection 27 which places the fuse under a leverage or binding stress,

then being inserted into a slot in the free end.

the other terminal of the fuse of spring 15 which is adapted to firmly grip the terminal of the fuse-26 and thereby securely hold the latter in place. Each fan- 'ning" strip 8 is provided on .its inner surface with a strip of insulation 28 having holes 29 29'therein concentric with holes 10 10 in strip 8 but somewhat smaller than holes 10 -10 so as to insulate conductors passing through holes 10 10, from the sheet metal 30 thereon formed preferably as shown. The cable conductors31 31 extend from the inclosure of box 1 through hollow posts'13 13 as'sho'wn in Fig. 3, and are soldered to the outer ends of posts'13 13 at 32 32, the solder sealing the holes in the posts 13 13. By thus soldering theconductois 31131 on the out- Sld of the box 1 the latter may be made much smaller than where the soldering is done within the-box 1 A muchbetterjob an be done where the soldering is done as shown in Fig. 3. "A thin sheet of fiber 33' is placed within the boxporti'on 1' as shownin Fig. 2; so astolprovide an insulatingsurface or lining for the box portion to protect the cable conductors 31 31 from the metal part 1.

\Vhen it isdesiredf to distribute the cable conductors 31-31 through the'hollow posts '13 13, the front cover'4 of the box .ortion to the interior of the box '1.

' the circuit ofa cable conductor 31 is extend ed through a hollow closed fuse 26,spring 25, and terminal 35, to a conductor 36 which extends to the aerial circuit.

The base plate 11 is pi'eferably'connected to ground toprovide a ground connection from ground stri s 19 19 for the li htning arresters 21' 21. v e-functions of the inclosed are inserted between the.

-fnses 26 26 and lightning arresters 21 21 in the'arrangement herein shown are well understood and it is not thought to be necessary .to go intoa detailed description of their uses as protective devices for the cable conductors.

At the lower end of the front plate 4 is secured a stifl spring member 37 preferably formed as shown in Fig. 1 and having a tongue portion 38 thereon near its up er end. Toward the u per end of the front p ate 4 is secured 'anot er spring member 39 which bears against the spring member 37 preterably as shown the tongue portion 33 prpjec't- 'ing through the outer end of spring member 39- A cylindrical sheet-metal cover 40 is placed over the terminal as a whole, prefer ably as shown in the drawings, it bearing against edge portions 41 41of fanning strips 8- 8, and the spring member 37, all of which for. the cover 40, thegsprin member 37 being under tension'from' itsell and from spring 39 which securely holds the cover 40 to the portions 41, 41 and 37, and at the same -time permits of the cover 40 being raised any desired amount. When the cover 40is entirely removedfrom the terminal the spring 37 takes the position 37 shown in dotted lines in Fig. 1. When it'is desired to place the cover 40 over the terminal; the spring 37 is'pressed from the position 37 to the position 37 whence the cover 40 maybe readily lowered over'the ter1ninal.- When it is desired to raise the cover 40 so as to expose the whole terminal, it is raise until the rim 44 thereof rests the notch 2 in spring 37 and in the recesses 43 43 in fanning strips 8- 8, the spring 37 holding the cover 40 in this position and thereby eliminating the necessity of entirely removing the cover from the terminal. tirely remove the cover 40 from the terminal or lower it over the'latter, the front spring 37 Now if it is desired to either en is pressed inwardly whereupon the cover 40 maybe readil moved either up or down.

It will rea ily be seen that the construction above described provides a very li ht cable terminal and acable terminal whic is very strong and readily accessible at all por- I tions. Such a cable terminal is also fire proof as it is constructed almost entirely of metal.
